Abstract

Many of the smaller electrostatographic reproducing machines are designed with a clam shell architecture including both upper and lower machine frames to provide access to the inner workings of the reproducing apparatus when the upper half is pivoted to the open position relative to the lower half. In addition, a number of these machines include a used toner collection system together with a used toner sump bottle for storing the used toner. The figures illustrate such a general configuration wherein the toner sump bottle 10 is contained in the lower half 12 of the machine. In Figure 1 the toner falls into the one end of the sump bottle 10 and tends to build up there occupying only a small percentage of the total volume of the toner sump bottle. To allevate this, Figure 2 shows the sump bottle 10 fastened to the upper part 14 of the machine so that when the clam shell machine is opened with the upper frame member being pivoted relative to the lower frame member, toner may slide down the sump bottle into the end of the toner sump section thereby freeing the other end. However, it has been found that in order for this to happen the angle between the lower frame member and the upper frame member must be in excess of about 32 . In those mackine geometries where this is not possible, Figure 3 provides an additional 10 to 15 increase in the hinqed angle at the entrance to the sump by hinging the top of the sump bottle 10 only to the upper half 14 of the clam shell permitting the bottom portion of the toner sump bottle to slide along the base of the lower machine half 12 frame. In this way, it is ensured that the toner slide to the collection end of the sump bottle.
